While it overlaps with code standards, it also involves <strong>higher-level design principles for writing consistent and maintainable code<\/strong>.<\/p>\n<p>All of these concepts are relevant to code sniffing. However, it\u2019s important to note that sniffing code <strong>won\u2019t necessarily identify runtime bugs<\/strong> because its primary focus is on <strong>ensuring strict compliance with coding standards<\/strong>.<\/p>\n<p>You might be wondering, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/paul-m-jones.com\/post\/2004\/09\/23\/why-coding-standards-matter\/\">do standards even matter<\/a>? The answer is yes, particularly for optimization and project clean-up. Many developers agree that coding standards are essential in programming and web development, especially on large team projects.<\/p>\n<p>Developer <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/paul-m-jones.com\/post\/2004\/09\/23\/why-coding-standards-matter\/\">Paul Jones<\/a> explains the importance of code standards:<\/p>\n<p><em>\u201cThe point of a coding style standard is not to say one style is objectively better than another\u2026 Instead, the point is to set up known expectations on how code is going to look.\u201d<\/em><\/p>\n<p>If you\u2019re developing a small web app for personal use, it might not seem necessary to follow standards like <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.w3.org\/TR\/WCAG\/\">WCAG 2.0<\/a> or <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.php-fig.org\/psr\/psr-2\/\">PSR-2<\/a>. However, consider the hundreds of developers working on Adobe Photoshop\u2019s source code. It would be chaotic if each person wrote code in their own style and then tried to merge it all together.<\/p>\n<p>While teams heavily rely on standards, these rules can also benefit individual developers. Code standards exist for everything from CSS to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/WordPress\/WordPress-Coding-Standards\">WordPress<\/a>, so there\u2019s no reason not to try them out and see how they can improve your code quality.<\/p>\n<h2>The Importance of Code Standards<\/h2>\n<p>Adhering to code standards naturally <strong>keeps your code clean and organized<\/strong>. Developers can easily write, read, and follow each other\u2019s work, making collaboration smoother.<\/p>\n<p>Code standards also benefit open-source development by providing clear guidelines for others to follow. <strong>Files can be revisited by anyone months or even years later, and they will still be easy to understand<\/strong>.<\/p>\n<p>Maintaining a strict coding style is advisable, <strong>even if you create your own<\/strong>. While it requires effort, this type of documentation becomes invaluable as projects grow in size and complexity.<\/p>\n<p>Here are some coding standards to consider across various web languages:<\/p>\n<ul>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pear.php.net\/manual\/en\/standards.php\">PEAR Coding Standards (PHP)<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/google.github.io\/styleguide\/htmlcssguide.xml\">Google Standards for HTML\/CSS<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/google.github.io\/styleguide\/javascriptguide.xml\">Google Standards for JavaScript<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.djangoproject.com\/internals\/contributing\/writing-code\/coding-style\/\">Django Coding Style (Python)<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/rubocop\/rails-style-guide\">Rails Style Guide (Ruby)<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.w3.org\/TR\/UNDERSTANDING-WCAG20\/conformance.html\">WCAG 2.0 (UX)<\/a><\/li>\n<\/ul>\n<h2>Top Resources for Code Sniffing<\/h2>\n<p>Today, you can find free code sniffers for almost everything, from HTML\/CSS to backend languages like PHP and SQL.

These tools check for syntax errors rather than code standards, but they are also highly beneficial for frontend code optimization.<\/p>\n<p>For reference, it\u2019s also possible to check JS\/CSS standards <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/gregsherwood.blogspot.com\/2009\/09\/why-check-javascript-and-css-files-with.html\">directly with PHP_CodeSniffer<\/a>.<\/p>\n<h3>The PHP Code Sniffer<\/h3>\n<p><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pear.php.net\/manual\/en\/package.php.php-codesniffer.faq.php\">PHP_CodeSniffer<\/a> is an essential tool if you\u2019re aiming to comply with PHP coding standards. The package includes several <strong>PHP scripts that analyze PHP, JS, and CSS code for compliance<\/strong> with your chosen code style guidelines.<\/p>\n<p>The creator of PHP_CodeSniffer, Greg Sherwood, shared a <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/stackoverflow.com\/a\/5985349\/477958\">great backstory<\/a> about how the idea came to life and the issues it addresses (a recommended read if you have the time).<\/p>\n<p>In summary, Greg\u2019s team was learning JavaScript integrated into a PHP app, aiming to structure the JS code to follow PHP standards for easier switching between languages. This led to the creation of <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/squizlabs\/PHP_CodeSniffer\">PHP_CodeSniffer<\/a>.<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/assets.hongkiat.com\/uploads\/code-optimization-code-sniffers\/03-code-sniffer-app-testing-code.jpg\" alt=\"PHP CodeSniffer screenshot\" width=\"700\" height=\"400\"><\/figure>\n<p>This is especially useful for PHP developers since <strong>the language is relatively lenient with mandatory style requirements<\/strong>. While frameworks like <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/laravel.com\/\">Laravel<\/a> enforce stricter guidelines, developers should still establish their own coding standards rather than relying solely on third-party frameworks.<\/p>\n<p>Popular standards like <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/php-fig\/fig-standards\/blob\/master\/accepted\/PSR-0.md\">PSR-0<\/a>, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/php-fig\/fig-standards\/blob\/master\/accepted\/PSR-1-basic-coding-standard.md\">PSR-1<\/a>, and <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/php-fig\/fig-standards\/blob\/master\/accepted\/PSR-2-coding-style-guide.md\">PSR-2<\/a> are all widely used and are included with the PHP sniffing library.<\/p>\n<p>However, you can find many other pre-configured code standards for PHP CMS platforms like <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/WordPress\/WordPress-Coding-Standards\">WordPress<\/a>, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/magento-ecg\/coding-standard\">Magento<\/a>, and <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.drupal.org\/node\/1419988\">Drupal<\/a>. Drupal core developers even released an official code sniffer module called <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.drupal.org\/project\/coder\">Coder<\/a>.<\/p>\n<p>PHP is undoubtedly one of the easiest languages to optimize with code sniffers. If you\u2019re looking for <strong>a comprehensive list of PHP code standards<\/strong>, check out <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/php-fig\/fig-standards\">this GitHub repository<\/a>.<\/p>\n<h3>Other Backend Code Sniffers<\/h3>\n<p>Backend developers work with various languages beyond PHP, and the number of these languages is growing each year. Along with these alternative languages come different code sniffing libraries, such as <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pypi.python.org\/pypi\/code-sniffer\/\">code-sniffer<\/a> for Python.<\/p>\n<p>You can find <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/stackoverflow.com\/a\/1318939\/477958\">other scripts online<\/a> or use tools like <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.pylint.org\/\">PyLint<\/a>. However, integrating this methodology into your development flow requires patience.<\/p>\n<figure><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.pylint.org\/\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/assets.hongkiat.com\/uploads\/code-optimization-code-sniffers\/04-pylint-console-python.jpg\" alt=\"PyLint console web app\" width=\"700\" height=\"400\"><\/a><\/figure>\n<p>Ruby developers also have a <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/stackoverflow.com\/a\/287064\/477958\">range of choices<\/a> for <strong>code linting and analysis<\/strong>. The best options are often free and open-source, such as <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/YorickPeterse\/ruby-lint\">Ruby Lint<\/a>, a static code analyzer for modern Ruby code.<\/p>\n<p>While I haven\u2019t found a dedicated <a href=\"https:\/\/www.hongkiat.com\/blog\/node-js-server-side-javascript\/\">Node.js<\/a> code sniffer yet, I\u2019m hopeful that a project will emerge in the future. There are <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/stackoverflow.com\/a\/20410172\/477958\">JS code sniffers<\/a> that support Node standards, but it\u2019s still a relatively new backend language that needs time to mature.<\/p>\n<p>Lastly, we have <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/stackoverflow.com\/q\/3970643\/477958\">SQL syntax<\/a> used in databases. This code can be trickier to standardize since it\u2019s challenging to find well-supported syntax standards for SQL. However, I did find a <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/sqlformat.org\/\">SQL formatting web app<\/a> that should prove immensely helpful when optimizing database queries.<\/p>\n<h2>Conclusion<\/h2>\n<p>The best way to start code sniffing is by focusing on one language and one standard. HTML\/CSS is a great starting point for frontend developers, while PHP is a popular choice among backend developers, especially those working with WordPress.<\/p>\n<p>If you want to learn more, check out these related posts on code sniffing, linting, and <a href=\"https:\/\/www.hongkiat.com\/blog\/tag\/code-optimization-series\/\">automated code analysis for optimization<\/a>.<\/p>\n<ul>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.sitepoint.com\/coding-standards\/\">Why You Need Coding Standards<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/blog.codinghorror.com\/code-smells\/\">Code Smells by Jeff Atwood<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/scrutinizer-ci.com\/docs\/tools\/php\/code-sniffer\/\">PHP Code Sniffer: Installation & Configuration<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"http:\/\/www.kingkludge.net\/2009\/01\/codesniffer-part-1-introduction-to-codesniffer\/\">Introduction to CodeSniffer (Part 1)<\/a><\/li>\n<li><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/github.com\/collections\/clean-code-linters\">GitHub Showcase: Clean Code Linters<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Editor\u2019s note: This article is part of our Code Optimization series, where we explore how to optimize code for better efficiency, helping you become a more effective coder.
